Sphere in Hand: Exploring Tangible Interaction with Immersive Spherical Visualizations
In Extended Abstracts of the 26th IEEE Conference on Virtual Reality and 3D User Interfaces (IEEE VR 2019). Osaka, Japan, March 23 - 27, 2019.

Spherical visualizations allow for convenient exploration of certain types of data. Our tangible sphere, exactly aligned with the sphere visualizations shown in VR, implements a very natural way of interaction and utilizes senses and skills trained in the real world. This work is motivated by the prospect to create in VR a low-cost, tangible, robust, handheld spherical display that would be difficult or impossible to implement as a physical display. Our concept enables it to gain insights about the impact of a fully tangible embodiment of a virtual object on. We discuss the advantages and disadvantages of our approach, taking into account different handheld spherical displays utilizing outside and inside projection.
